[Schema Inaccuracy] pages-deployment requestBody schema doesn't match example

Abre descriptions-next/ghes-3.13/ghes-3.13.json e inspecciona el esquema requestBody y el ejemplo predeterminado en los punteros JSON indicados en el issue. Compara las definiciones correspondientes en las versiones de GHES enumeradas y, a continuación, alinea el esquema y el ejemplo para que el campo preview se represente de forma coherente.

Schema Inaccuracy

At this location, the schema has 4 fields - artifact_url, environment, pages_build_version, oidc_token.

#/paths/~1repos~1{owner}~1{repo}~1pages~1deployments/post/requestBody/content/application~1json/schema

The example here as a fifth field

#/paths/~1repos~1{owner}~1{repo}~1pages~1deployments/post/requestBody/content/application~1json/examples/default/value
